The document discusses 7 principles of web design: unity, variety, balance, scale and proportion, rhythm, emphasis, and simplicity. Unity is achieved through consistent use of colors and shapes, as seen on Coca Cola's website. Variety is provided by unique elements that change during website scrolling. Balance is demonstrated on Wikipedia through white space and focal points aligned around the page. Scale and proportion relate image and text sizes, as on WarChild. Rhythm creates flowing organization, like the boxes on Pinterest. Emphasis draws the eye to significant elements, such as large videos on YouTube. Simplicity is found on Tumblr through clean login placement in the center.
